Dunlop SX 300

Meet the next generation of spin. The Dunlop SX 300 meets the needs of modern players, providing more spin on off-center shots to keep the ball in the court. This edition improves the previous version with technologies that improve comfort and spin generation. Stay consistent on attacking shots as the Spin Boost+ Grommets and Spin boost string tech perfectly blend power and spin. If you're looking to hit more winners and less errors, join the spin generation with the Dunlop SX 300!

Who's it for?

  • Tennis players who hit the ball with normal-to-long swings and want a balance of spin and power.

Racquet Technology

  • Spin Boost+ Grommets: Dynamic set of spin-enhancing grommets work with the spin boost string tech to provide more power, spin and control. The grommets allow for more string movement, creating a 'bite' on the ball, thus generating more spin. The extra movement makes the string bed more forgiving, creating a larger sweet spot.
  • Spin Boost String tech: Innovative enlargement of the string bed creates a more even power distribution and spin generation. This effect transfers more power to the top of the racquet where its needed for spin generation.
  • V-Energy Shaft: Unique V Shape frame geometry in the shaft of the racquet enhances frame stability and power.
  • Sonic Core™ made with Infinergy® by BASF: Material placed in the 2 and 10 o'clock areas of the racquet to offer high rebound and reduced vibrations, helping you unleash game-winning shots at will.
